MakerBot Gen4 Interface Board 4-direction Center push

I designed MakerBot Gen4 Interface Board small.

I found 2ch LCD MODULE and 4 direction Switch and flashed.
Pin assignment of the LCD is original MIB and compatible.
The LCD should work with the original MIB just plugging the cable.
I think that I can use it when I place an LCD cable of original MIB.
I do not test it.

I attached a backlight switch to the LCD.
